Story summary

One person has died and four others are injured after a landslide was triggered by heavy rain in the city of Geoje, South Korea, which received almost a meter (800mm) of rain over the weekend. The rain caused a landslide that hit an apartment building, with three residents rescued but one pronounced dead at a hospital. The heavy downpours have also forced the evacuation of about 390 people and caused power outages for around 3,580 houses in southern South Korea's South Gyeongsang province. Overall, 912mm of rain has been recorded in the region by Monday evening, with Geoje receiving 805.7mm and nearby Tongyeong getting 671.9mm over a two-day period. The excessive rainfall is so severe that it's equivalent to an entire summer's worth of rain for South Gyeongsang province in just two days, according to weather officials quoted by the Korea Herald.
